Flagstone City is a 500 ha+ development located at Jimboomba which on completion will include  a selection of neighbourhoods, schools, a  city centre that will feature all the services and amenities of a major regional centre, parks and green space.

ALLROADS were initially awarded the contract to undertake stage 1E works in February 2017, then additional 1F to 1J bulk earthworks and civil works packages followed, incorporating 187 lots with specific works including: bulk earthworks, rock management and processing, retaining walls, stormwater, sewer, water reticulation, gravel placement and asphalting.

The rock management component of the works provided a number of challenges due to the high strength nature of the rock and close proximity of residential housing and trench excavations up to 6m deep were required. To help overcome this, drill, blast and crush operations were performed in varying depths of up to 8m deep. 

As the Flagstone Development is an Economic Development Queensland (EDQ) approved development, environmental management, traffic management and stakeholder management was critical in undertaking the works.  ALLROADS closely monitored construction works ensuring relevant public interface, traffic, and environmental controls were being implemented as per the EDQ approved Project Management Plan.
